To tu whont it rita/y concern:

Be it known that I, CHARLES MCGREGOR, a citizen of the United States, residing at Nashua, in the county of Hillsboro, State of New Hampshire, have invented certain new and useful Improvements in Wind-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to windmills; and my object is to provide a wind-motor of greatest possible power consistent with the employment of a minium number of cooperating elements; and with this object in view my invention consists of certain novel features of combination and construction of parts, the preferred physical embodiment whereof will be set forth in the following specification, pointed out in the claims, and illustrated in the accompanying drawings, in which- Figure l is a front elevation of my invention complete. Fig. 2 is a central vertical section of Fig. 1 on line @c oc, while Fig. 3 is a horizontal section of Fig. 2, taken on line y y.

The essential feature of my invention and the elements deemed necessary to illustrate a practical application thereof to use will each be designated by a reference-numeral, of which- 1 indicates the supporting-base or tower of the usual or any preferred form, designed to aord a suitable support for the parts of my wind-motor proper. Said base is provided with a suitable socket 2, tubular in form and open at its upper end, and thus adapted to receive the lower end 3 of the hub of the horizontally-disposed beveled gear 4, the upper end 5 of said hub -being thus disposed in proper position to receive the pump-rod or piston 6, which extends loosely downward therethrough to the pump or other mechanism to be operated thereby. The upper end 5 of the hub is adapted for the additional purpose of affording a suitable support or seat for the carrying-frame, comprising in this instance the base members 7 and 8, the upright sections 9 and 10, and the top section or rod 1l, connecting the upper ends of said uprights. It will be understood that this frame may be made in any preferred way and of any desired material, though it is thought best results will be attained by the use of suitable tubing, inasmuch as a greater degree of strength consistent with lightness will be possible. The inner ends of the members 7 and 8 may be rigidly and securely connected to the hub-section 5 by threading said ends into the seats 12, integrally formed with said hub, the outer ends of said members being connected to the uprights 9 and 10 by the T and angle couplings 13 and 14, respectively. In like manner the uprights 9 and l0 are connected to the top section by the angle-couplings l5. If deemed desirable, the members 7 and 8 may be reinforced by the connecting-links 16 and 17, as illustrated in Fig. 1. This carryingframe or the equivalent thereof is thus securely mounted in its operative position, so that it will rotate or bodily turn upon its axis, which in the present case comprises the lower end 3 of the hub of the wheel 4., and desiring to utilize the rotation of the frame I suspend from the upper section or rod 11 a pair of swinging or reciprocating fans or wind engaging blades 18 and 19. Said fans are operatively suspended in position by means of the rods or arms 20, which are rigidly connected to said fans and also rigidly joined at their upper ends to the rocking bar 21, which latter is properly suspended by means of the ears or brackets 22, connected to or forming an integral part of said bar. It will be observedv that said ears are provided with apertures adapted to loosely receive the section 11 of the frame, as illustrated in Fig. 1. By this arrangement it will be seen that the bar 2l is adapted to swing freely upon the rod 11, and I utilize this rocking movement of said bar to actuate the piston or pump-rod 6 through the mediation of the link-section28, which is pivotally connected to the pump-rod, as indicated by the numeral 24., while the upper end of the link is pivotally connected to the under side of the rocking bar 21, preferably by means of the swivel 25. By thus providing this swivel or universal jointintermediate the pump-rod and the rocking bar it is obvious that the carrying-frame may freely IOO rotate upon its axis without twisting said rod, as would be the case if a simple form of pivotal union was adopted.

By the combination of parts as above presented it will be clearly apparent that if a swivel or oscillating movement is imparted to the blades 18 and 19 the result will be a rocking Ymovement of the bar 21 and incidentally a reciprocation of the piston or pumprod, inasmuch as the lower side of said bar will describe the arc of a circle,thereby swinging the upper end of the link 23 alternately to the right and left in' said arc. It therefore becomes desirable to provide positive means for directing the movement of the carryingframe whereby said frame will be contin uously rotated or turned upon its axis, and thereby alternately present each side of the blades to the wind, and thus insure that said blades will be regularly swung to and fro in a pendulum-like movement. With this object in view I provide the beveled gear 26, designed to mesh with the beveled gear 4, the said gear 26 being keyed upon the shaft 27, which latter is provided with suitable bearings 28, disposed upon the upper side of the vane-arm 29. To the outer end of the shaft 27 I rigidly connect the wind-wheel 30, while the inner end of said vane-arm 29 is provided with the collar 31, adapted to surround and rotate upon the tubular socket l2. It will therefore be clearly apparent by reference to the drawings that the wind wheel 30 will act as a controlling-vane for my improved wind-motor, thereby positively insuring that the carrying-frame will always be disposed intermediate the vane and the wind. A further office of the vane or wind-wheel 30 is to continuously rotate the carrying-frame through the mediation of the shaft 27 and the gears et and 26, turning said frame upon its axis, and thereby alternately present the opposite sides of the blades 18 and 19 to the force of the wind, which will result in successively raising and lowering the pump-rod and operate the pump or other machinery with which said rod is connected. In Fig. 2 the direction of the Wind is designated by an arrow and the swinging blades shown outwardly extended by dotted lines, the corresponding position and accessories also being indicated in said manner. The arc of travel of the pivot-point of the bar 21 and the link 23 is also designated in Fig. 2 by a dotted line, and it will be observed that a positive alternate lifting and lowering of the piston follows.

It will be obvious that any suitable form of device or devices may be placed in coperation with certain parts of the mechanism herein illustrated and described, whereby said mechanism may be thrown in or out of gear at the pleasure of the operator, and since such stopping mechanism may be of the usual or any preferred construction I deem it unnecessary for the purpose of this application to particularize with reference thereto.

While it is the purpose of this specication to set forth the preferred combination and construction of the elements deemed necessary in carrying my invention into practical use, I desire to secure such possible substitutes and equivalents as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
